Zipp 303 Firecrest Carbon Rear Tubeless Wheel

Zipp 303 Firecrest Carbon Tubeless Rear Wheel

Engineered to meet the demands of modern road bike adventures, this rear wheel features a hookless carbon rim construction, which allows it to deliver incredibly fast and smooth rolling performance. Zipp has equipped this model with tubeless tyre compatibility, so you can enjoy the benefits of superior stability and control as well as a lighter overall weight. Another highlight of this version is its disc brake compatibility, which means that you’ll benefit from powerful and consistent braking performance during the most unpredictable of road conditions.

Zipp’s 303 Firecrest® Tubeless Disc-brake rear wheel is designed for the real world… a world of imperfect conditions, road surfaces, and elements where the bottom line is simple. Efficiency = speed. It’s faster, lighter, and more capable over varied terrain—whether the surface is pavement in all its conditions or no pavement at all. Deeply rooted in Zipp’s drive to conquer the Spring Classics, the 303 Firecrest is remade with a purpose-made approach for the demands of modern road bikes. When it comes to going fast on a bicycle, efficiency means reduced: Wind resistance, rolling resistance, rider fatigue, weight.

Designed using real-world direct measurements (vs. primarily wind tunnel or computer simulation). The results were huge. Its rim is slightly more bulbous in design than its predecessor, with a 30mm outside width, a 25mm internal width, and a 40mm rim depth. The profile provides low drag and an improved transition between rim and tyre, boosting aero efficiency on the road. The wide rim stance also features less tyre deflection for reduced rolling resistance. The combination of the wider tyre, increased tyre volume, and lower tyre pressure helps to reduce rider fatigue by smoothing out the ride over imperfect pavement and road conditions—the tyre and wheel system absorbs the shaking, not the rider.

At the centre of the 303 Firecrest Tubeless Disc brake rear wheel is a versatile and durable hubset, the German-engineered ZR1 DB. This hubset features 66 points of engagement for quicker response. The 303 Firecrest Tubeless Disc-brake rear wheel is for dedicated cyclists who aspire to the latest in technology. Its competitors… in races, against peers, or simply conquering personal limits. This is about becoming faster and matching your motivation to the most advanced technology.
